Abstract
A method and apparatus of filing beer for craft breweries combines pressurized beer delivery (rather than gravity feed) with variable pressure control of the beer flow into the can. By modulating beer flow and especially beer pressure, it is possible to fill a can's widget (gas reservoir) with gas with a shorter set of fill steps. In addition, the speed of beer filling can be dramatically increased compared to small scale systems normally used by craft brewers. Unlike known large scale pressure systems, the beer bowl may be located beneath the rest of the apparatus and modulated pressure may be used, making for a smaller and more portable unit.
